About “Epic Bosses”

Epic Bosses are villains that will only appear once all threats and deploys in a mission have been completed. Some of the deploys require a hero of a specific class or a specific Hero to be completed; each of these are listed on the appropriate Epic Boss.

If any of the deploys remain uncompleted when the last threat is done, the Epic Boss will not appear, so these must be completed as quickly as possible after they show up.
